Joseph P. Bradley, United States v. Perot — Opinion of the Court
“ If any doubt existed as to the extent of the Mexican league, an inquiry might be necessary to ascertain it. But no such doubt exists. The old legal league, by the laws of Spain, and which was adopted in Mexico, consisted of 5,000 varas; and a vara in Texas has always been regarded as equivalent to 33 1/3 English inches, making the league equal to a little more than 2.63 miles, and the square league equal to 4,428 4/10 acres. This is perfectly well understood in Texas, where controversies respecting Spanish titles are constantly brought before the courts. ”
